Answer:
The answer is 358.01
Step-by-step explanation:
Given:
![3\times 10^{2}+5\times 10^{1}+8\times 10^{0}+1\times \frac{1}{10^{2}}](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E%7B2%7D%2B5%5Ctimes%2010%5E%7B1%7D%2B8%5Ctimes%2010%5E%7B0%7D%2B1%5Ctimes%20%5Cfrac%7B1%7D%7B10%5E%7B2%7D%7D)
Now, to solve first we crack the power notation then multiply and then do the addition:
![3\times 100+5\times 10+8\times 1+1\times \frac{1}{100}](https://tex.z-dn.net/?f=3%5Ctimes%20100%2B5%5Ctimes%2010%2B8%5Ctimes%201%2B1%5Ctimes%20%5Cfrac%7B1%7D%7B100%7D)
(The value of
is 10 and the value of
is 1.)
![=300+50+8+\frac{1}{100}](https://tex.z-dn.net/?f=%3D300%2B50%2B8%2B%5Cfrac%7B1%7D%7B100%7D)
![=300+50+8+0.01](https://tex.z-dn.net/?f=%3D300%2B50%2B8%2B0.01)
.
Therefore, the answer is 358.01 .
Answer:
C. h + k (t - 1)
Step-by-step explanation:
<em>If we use an example, you can plug in the numbers and test out which equation works. Say the first hours costs $10 and each hour after that is an additional $5. If someone rents a jet ski for 4 hours, how much did it cost?</em>
The first hour = $10
The 3 additional hours (totaled) = $15
Cost = $25
<em />
<em>So now that we know the cost, we can plug in our numbers to these equations to find which one comes out with $25.</em>
h = 10
k = 5
t = 4
<u>A</u>. 10 + 4 + 5 = <u>19</u>
<u>B</u>. 10 + (4 · 5) = 10 + 20 = <u>30</u>
<u>C</u>. 10 + 5 (4 - 1) = 10 + 5 (3) = 10 + 15 = <u>25</u>
<u>D</u>. 10 + 5 (4 + 1) = 10 + 5 (5) = 10 + 25 = <u>35</u>
<u>E</u>. 10 + (4/5 - 1) = 10 + (-0.2) = <u>9.8</u>
<em>C is the only problem that comes out as $25, therefore it must be the correct answer.</em>
Answer:
![\± \sqrt{x + 7}](https://tex.z-dn.net/?f=%5C%C2%B1%20%5Csqrt%7Bx%20%2B%207%7D)
Step-by-step explanation:
y = x² - 7
Add 7 to both sides.
y + 7 = x²
Take square root on both sides.
±√(y + 7) = x
Switch variables.
±√(x + 7) = y
Step-by-step explanation:
1)
2 1/10 + 3/100 = 200/100 + 10/100 + 3/100 = 213/100 =
= 2 13/100
2)
2 1/10 + 5 3/100 = 200/100 + 10/100 + 500/100 + 3/100 =
= 713/100 = 7 13/100
3)
2.1 + 00.3 = 2.4
or did you mean + 100.3 ? then is is 102.4
4)
24/100 + 7/10 = 24/100 + 70/100 = 94/100 = 47/50
5)
3 24/100 + 8 7/10 =
= 300/100 + 24/100 + 800/100 + 70/100 =
= 1194/100 = 11 94/100 = 11 47/50
